Title: Corrosion-resistant composite wire and method for manufacturing same
Inventor: MUELLER VOLKER
IPC: B23K9/013
Filed: 1993-03-31
Abstract: Abstract Corrosion-resistant Composite Wire and Method for Manufacturing Same The object of the invention is a corrosion-resistant composite wire with diameters of<10mm which has a concentric and homogeneous high-grade steel coating, whereby a variation of this coating by 15 - 30% by volume is possible depending on the wire diameter and application in each case and also a variation of the strength of up to < 2000 N/mm2 depending on the core wire used and degree of shaping.  To manufacture a composite wire of this type, a high-strength, patented and surface-treated steel wire is, for example, sheathed when passing with a high-grade steel band.  In a first shaping step, the longitudinally welded high-grade steel sheath is firmly pressed against the core wire and the composite wire is drawn to end dimensions in subsequent drawing steps.  A directed annealing treatment of the composite wire takes place at least between two shaping steps by means of a rotating arc, whereby only the high-grade steel layer is heated to annealing temperature.

Title: Fabric useful as a concrete form liner
Inventor: SERAFINI FRANCO L
IPC: B28B7/36
Filed: 1991-12-10
Abstract: Concrete forms utilizing an improved concrete form liner comprising a two-sided fabric having a different range of pore sizes on one side compared to the opposite side. In one embodiment, a microporous coating, such as an ethylene-vinyl chloride microfoam dispersion, is placed on one side of a porous fabric (13) to controllably reduce the pore size of the fabric (13) on that side to between 0.2 to 20 microns. The coated fabric is used in combination with a support (11) and a grid (12) to form a concrete casting system (10) wherein the coated side of the fabric (13) is placed directly in contact with the concrete. The microporous coating stabilizes the surface fibers of the fabric (13) thereby reducing the tendency of the fibers to stick to the concrete. The pore size of the coated side of the fabric must be small enough to substantially keep all concrete particles from passing through the fabric, but sufficiently open to permit the passage of water and air.

Title: Process for the preparation of high molecular weight polyesters
Inventor: HOMANN WALTER K
IPC: C08G63/88
Filed: 1994-03-11
Abstract: Abstract A process for preparing high molecular weight polyesters is disclosed.  In the process, an aromatic acid is first polycondensated with a mixture of alkane- and alkenediols in the presence of a catalyst and in the absence of oxygen, to obtain a polyester having a viscosity number of from about 50 to about 140 cm3/g.  A free radicals forming agent is then added to the polyester which is further reacted in the melt until a predetermined final viscosity number, usually less than 400 cm3/g, is obtained.  The agent is so selected as to dissociate with a half life of from 5 seconds to 120 minutes at temperatures from 130 to 350°C.  The process, which does not adversely affect the properties of polyester, such as heat and mechanical stability, processing stability or colour, allows to achieve the required high viscosity number quickly and in a controlled manner.  The process is particularly useful for preparing small amounts of high molecular weight polyester.

Abstract: This invention provides processes for making three-dimensional signage. In one embodiment, a process is provided for making raised graphic signage. In this embodiment, a profile material (12) is adhered to a substrate material (10) with an adhesive (14) which:  (a) bonds firmly enough to hold the profile (12) and substrate materials (10) together during the process, (b) permits the profile (12) and substrate material (10) to be separated after the process is completed, and (c) cures to form a more permanent bond after the profile (12) and substrate materials (10) have been separated. Then, an outline of a desired graphic is cut completely throug the profile material (12). That portion of the profile material (12) which does not constitute the outlined graphic is then separated from the substrate material (10), before the adhesive forms a permanent bond. In another embodiment, a process is provided for making recessed graphic signage. This embodiment is similar to the former, except that, after an outline of a desired graphic is cut completely through the profile material (12), that portion of the profile material (12) which constitutes the outlined graphic is separated from the substrate material (10), before the adhesive forms a permanent bond. When practicing either embodiment of this invention, the alignment and registration of the letters, numbers and graphics are maintained.

Title: Longwall mining roof control system
Inventor: CALANDRA FRANK JR
IPC: E21C41/16
Filed: 1994-10-27
Abstract: ABSTRACT OF THE DISCLOSURE In a longwall mining operation, a panel to be extracted is formed in a seam of mine material by longitudinally extending headgate and tailgate entries with the panel beginning in a set up room and ending at a termination line in a recovery room.  The recovery room is developed in two stages.  In the first stage, the recovery room extends the transverse width of the panel and extends from the termination line a preselected distance to a first sidewall.  A roof control system is installed to support the rock strata over the initial width of the recovery room.  A primary support system includes mechanical roof bolt assemblies installed in accordance with a preselected bolt pattern.  The roof bolt assemblies are supplemented by trusses extending in spaced parallel relation a preselected distance apart from the termination line to the first sidewall.   Channel members are secured in end to end relation to the roof closely adjacent to and parallel to the first sidewall.  Thereafter, the width of the recovery room is expanded to approximately twice the initial width.   The roof above the expanded width of the recovery room is supported with a system complementary to the system initially installed including roof bolt assemblies, trusses and channel members.  This system supports the roof of the recovery room to withstand the abutment pressures generated as the longwall shearers break through the termination line.
